Understanding Ventura County’s Climate

Ventura County, located along the Southern California coast, enjoys a Mediterranean climate, characterized by mild, wet winters and warm, dry summers. However, due to the region’s diverse geography, weather conditions can vary significantly depending on whether you are by the coast, inland, or in the mountainous areas.

Coastal Weather Patterns

The coastal cities, including Ventura, Oxnard, and Camarillo, experience mild temperatures year-round. Winters bring moderate rain, while summers stay pleasant with cool ocean breezes keeping temperatures comfortable. Daytime highs rarely exceed 80°F in the summer, while winters average around 60°F.

This region often experiences a phenomenon called the marine layer, especially in the late spring and early summer months. This weather pattern brings fog and low clouds in the morning, which usually burns off by midday, revealing sunny skies.

Inland Weather Variations

As you move further inland toward Simi Valley or Thousand Oaks, the weather becomes more continental, with hotter summers and cooler winters. Inland temperatures can reach the mid-90s°F in the summer months, though the nights tend to cool off. The inland areas experience fewer coastal influences, making them warmer and drier throughout the year.

Mountainous and High-Altitude Conditions

The Santa Monica Mountains and other high-altitude areas in Ventura County bring unique weather conditions. The higher elevation results in cooler temperatures and slightly more precipitation than the surrounding valleys and coastal regions. In winter, these areas may experience frost, and on rare occasions, light snowfall can blanket the mountain peaks.

Seasonal Weather in Ventura County

To help you plan your year, here’s an in-depth look at the seasonal weather patterns you can expect across Ventura County.

Spring (March – May)

Spring in Ventura County is a time of transition. As winter rains taper off, the county begins to warm up, especially in the inland and valley regions. March and April can still bring occasional rain showers, but the sun dominates the forecast as the season progresses. By May, Ventura County starts to see the arrival of the marine layer along the coast, leading to foggy mornings that clear by the afternoon.

• Average Temperature: 55°F – 75°F
• Rainfall: Light to moderate showers in early spring
• What to Expect: Cooler mornings, warming afternoons, occasional rain

Summer (June – August)

The summer months bring clear skies and warm temperatures, especially inland. However, coastal areas remain cooler thanks to the Pacific Ocean’s cooling effect. Expect dry conditions and plenty of sunshine throughout the county, making it the perfect time for beach outings or outdoor adventures.

In late summer, Santa Ana winds can occasionally sweep through Ventura County. These hot, dry winds originate inland and significantly raise temperatures, especially in the valleys. Fire danger is heightened during these periods, so it’s important to stay informed.

• Average Temperature: 60°F – 90°F (coastal) and 70°F – 100°F (inland)
• Rainfall: Minimal, almost non-existent
• What to Expect: Warm and dry days, particularly hot inland, mild along the coast

Fall (September – November)

Fall is a beautiful time in Ventura County, with clear skies and mild temperatures continuing through September and October. As the region transitions toward winter, temperatures begin to cool, especially in the evenings and at higher elevations.

By late October and into November, the Santa Ana winds may return, bringing dry, warm conditions from the interior desert regions. These winds create a high fire risk, so be mindful of fire warnings and advisories during this period.

• Average Temperature: 50°F – 85°F
• Rainfall: Light, occasional early fall showers
• What to Expect: Cooler mornings and evenings, Santa Ana winds, increasing fire risk

Winter (December – February)

Winter is the wettest season in Ventura County, with most of the annual rainfall occurring between December and February. While temperatures remain mild, especially along the coast, rainstorms can be frequent, particularly in January. Inland areas experience cooler temperatures, and the mountains may even see frost or occasional snow.

The coastal regions continue to see moderate daytime temperatures, while evenings can drop to the low 40s°F. Be prepared for potential rain showers and cooler nights during this season.

• Average Temperature: 45°F – 65°F
• Rainfall: Moderate to heavy rain, especially in January
• What to Expect: Cool and wet conditions, foggy mornings, rare mountain snow
